Problems solved by technology

When the pipeline is disassembled after unloading, the residual liquid in the pipeline will flow to the ground, which needs to be washed in time, and the flushing water will also cause pollution; at the same time, the centrifugal pump itself is prone to leakage, which will cause splashing and affect safety
In addition, the centrifugal pump must be filled with water (lye) before starting to work, but the alkali is highly corrosive, and the centrifugal pump is attached by alkali, which greatly shortens the life of the centrifugal pump

Embodiment Construction

[0031] The present case will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] This case involves a zero-leakage alkali unloading device, such as Figure 1-5 As shown, it mainly includes a frame 1 , a device main body 2 and a driving mechanism 3 . The device main body 2 and the driving mechanism 3 are both arranged on the frame 1 .

[0033] The device main body 2 mainly includes an organic casing 21 , a main shaft 22 and an impeller 23 . The casing 21 is in the shape of a volute (the rotation direction of the volute determines the direction of the alkali flow), and its side and the end of the volute are respectively provided with an alkali inlet pipeline 211 and an alkali outlet pipeline 212 . The main shaft 22 is arranged horizontally, one end of which is in transmission connection with the driving mechanism 3 , and the other end extends into the casing 21 along the axial direction of the casing. The plane...

Abstract

The invention discloses a zero-leakage alkali discharging device, which comprises a rack, a device body arranged on the rack and a driving mechanism, wherein the device body comprises a housing, an impeller and a main shaft; the housing is volute-shaped, and the side surface and the spiral tail end are provided with an alkali inlet pipeline and an alkali outlet pipeline; one end of the main shaft is in transmission connection with the driving mechanism, the other end of the main shaft extends into the housing along the axial direction of the housing, the impeller is arranged in the housing and axially arranged at the other end of the main shaft, and the impeller is driven to rotate by the driving mechanism through the main shaft. Compared with the prior art, the alkali discharging device disclosed by the invention has the advantages of zero leakage, high efficiency, environment protection, no residual solution, ability of reducing resource waste and environmental pollution and the like, has great economic values and application values and is wide in application prospect, thereby being an optimal choice for transporting chemical solutions in each industry.

Description

technical field [0001] The invention relates to an alkali unloading device, in particular to a zero-leakage alkali unloading device. Background technique [0002] At present, the transportation of corrosive lye has always been an industrial problem. 30% of the commercial lye (NaOH aqueous solution) is highly corrosive, and the tank truck it transports basically has no power (pump), and generally needs to be connected separately. Centrifugal pump for unloading. When the pipeline is disassembled after unloading, the residual liquid in the pipeline will flow to the ground, which needs to be washed in time, and the flushing water will also cause pollution; at the same time, the centrifugal pump itself is prone to leakage, which will cause splashing and affect safety. In addition, the centrifugal pump must be filled with water (lye) before starting to work, but the alkali is highly corrosive, and the centrifugal pump is attached by alkali, which greatly shortens the life of the ...
